S-Chassis.com - electrical problem please help

Well Now my AC turns on but nothing is coming out ever since i put in my Dash back in. Also the fuse box on the driver side under the steering wheel where the clutch is on the left side. does anyone know the layout and which each one does? cause I'm missing a bunch. Also my blinkers aren't working >.< nor coming out on the gauge thing(where the rpm and mph are) and another bad thing.. My car was on Empty and i know no one put gas in it. But when i install the gauge thing my gas goes all the way to half way tank? is it reading right? or My car before wasn't reading correct cause i did have many battery problems that cause my alternator to fray and other things.. Thanks... would be a big help of i can get at least the blinkers working and I hope the gas thing is right.. if not at least to show you need gas light on.
